ABSTRACT

The present invention relates to a method of digital film distribution and watching based on an online eye screen. A film distributor distributes film data and film broadcasting rights to a user. The user watches a film based on the film data and the film broadcasting right from the film distributor through the online eye screen. The online eye screen is a wearable display device. The present invention allows film distributors to distribute films to individuals directly, and better control the number of users per distribution right granted, and decreases the cost of film distribution. The present invention decreases piracy and infringement of films because the invention increases the difficulty of unauthorized video recording. The present invention also improves the user&#39;s visual effect and viewing experience by filtering the scene outside. The present invention allows user to watch films anywhere and at any time.

FIELD OF THE INVENTION

The present invention relates to film distribution and watching method based on an online eye screen. Movie viewers can obtain permission and/or data of films from film distributors directly, so that viewers can watch films anywhere and at any time.

BACKGROUND OF THE INVENTION

The cinema is a traditional film showing place. Cinema operators buy permissions and reels of films from film distributors, and release screen schedules to the public.

Cinemas show a specific film at a specific time according to a predetermined screen schedule. Movie viewers then watch films in a cinema with a movie ticket.

Generally, a plurality of cinemas and corresponding film distributors work with a theater chain to standardize the film schedule. In the first showing period, film distributors distribute films to cinemas only, which is the only way for customers to watch a new movie. One issue with the above method is that customers can watch films only in cinemas rather than anywhere and at any time. A second issue is that the customer can only watch specific films at certain corresponding times. It's very difficult for a customer to watch a film after the first showing period. In some instances it is not convenient or even possible for customers living in remote regions to go to cinemas.

After the first showing period, some films will have a second showing period on the internet. Video platforms add the film data into their server after gaining the necessary permissions from broadcasters. A user watches films via online streaming directly or after downloading the film through visiting video platforms' servers via mobile phones, computers or any number of other network terminals. However, the visual effects and viewing experience on a network terminal is far inferior to the visual effects and viewing experience in a cinema. At the same time, network terminals are capable of showing a movie to multiple people simultaneously by using large-size screen monitors. In this case, video platforms cannot figure out the number of people actually watching a film even if the total number of times a film was played can be exactly calculated. Thus, film distributors cannot record and count the number of people who are actually watching a particular movie. Further, illegal copying is also uncontrollable. In above two cases, the interests of the film distributors are damaged.

SUMMARY OF THE INVENTION

A digital film distribution and watching method based on an online eye screen of the present invention overcomes the issues stated above.

One objective of the present invention is to allow people to watch films anywhere and at any time. For example, people living in remote regions which have no cinema can also watch films conveniently.

Another objective of the present invention is to filter the scene outside the screen, which greatly improves the visual effect and viewing experience of watching films.

Another objective of the present invention is to control and calculate the number of people that have watched a film. Film distributors are able to charge according to the number of people actually watching, which protects the interests of film distributors. The present invention also increases the enthusiasm of film distributors to distribute films online simultaneously as the first showing period while the film is still in theaters. The wide coverage of online film distribution attracts more users and greatly decreases the cost of film distribution.

Another objective of the present invention is to decrease piracy and infringement of films by increasing the difficulty of video recording.

DETAIL DESCRIPTION OF THE INVENTION

FIG. 1 shows a digital film distribution and watching method based on an online eye screen. In FIG. 1, film distributor 30 distributes film data and film broadcasting rights to user 34, wherein said film broadcasting right is the right of broadcasting films through online eye screen 33. User 34 watches a film based on the film data and the film broadcasting rights from film distributor 30 through online eye screen 33. Online eye screen 33 is a wearable display device, wherein online eye screen 33 comprises a bracket which fits to a human's head. The bracket is equipped with video display device, wherein video display device is equipped with a display system and two headsets 6. The display system comprises screen 23, wherein screen 23 is located at the front of bracket and faces user's eyes. Headsets 6 are located at the left and right sides of the bracket respectively which face user's corresponding ears.

Film distributor 30 distributes film data and film broadcasting rights to customer 34 through multiple ways.

For example, film distributor 30 distributes carriers 31 (i.e. USB flash disk or mobile HDD) stored with film data. User 34 plays the films by connecting carriers 31 to online eye screen 33. Film broadcasting rights, can be acquiescent, namely carriers 31 can distribute the right of broadcasting for the corresponding film. The film broadcasting right can also be ostensive, for example, user 34 needs to input codes predetermined and set by film distributor 30, wherein codes can be recorded on cards which are distributed with carriers 31 by film distributor 30 at the same time. In this case, even if carries 31 are held illegally, films are still unable to be played without codes.

Playing times and/or playing periods of films can be limited by existing technology on carriers. For example, a film is limited to be played a certain number of times like one time, three times or any other number of times. A film can also be limited to be played within a period of time like two days, three days or any other time after the first play. Film data will be locked or destroyed if playing times or the playing period exceeds the predetermined limits. In this case, users are not able to broadcast the film endlessly with a single purchase, which protects the interests of film distributor 30. At the same time, film data is technically designed to be read only by online eye screen 33, namely, films are not able to be played by any other devices, so that illegitimate replication of film data is avoided.

As another example, film distributor 30 distributes film data and film broadcasting rights through film distributor platform 32. User 34 downloads film data to local-storage device so that user 34 can watch films whenever they want. Film data and film broadcasting right can be distributed simultaneously or separately. For example, film data is available through downloading from film distributor platform 32 at any time by anyone, however, the film can be played only if user 34 obtains the film's broadcasting right. There exist several methods to get film broadcasting rights. For example, user 34 receives a message after paying for a film online, wherein the message with a code is sent to user's mobile phone which is used to pay the fee. Only if the code of film is input into online eye screen 33, can the film be played. In another situation, online eye screen 33 with network communication functionality downloads codes or any other control data directly to play films. In another situation, User 34 is required to pay first, then user 34 can download and watch films.

Multiple terminals can be used to download film data from film distributor platform 32, like PC, mobile phones or any other terminals, to make fill use of network communication capability of existing facilities. In this situation, online eye screen 33 only requires film display capability rather than powerful network communication capability, which simplifies the configuration of online eye screen 33. User 34 can watch films online by online eye screen 33 through connecting to film distributor platform 32 if necessary, wherein online eye screen 33 has network communication capability and is qualified for network communication. In another case, user 34 connects online eye screen 33 to communication facilities with corresponding communication capabilities (like mobile phones) to connect to film distributor platform 32. Communication facilities obtain film data from film distributor platform 32 and transfer film data to online eye screen 33. Thus, customer 34 can watch films on online eye screen 33.

One or several of the multiple ways of film distributing stated above can be selected to be put into effect.

To control film broadcasting rights, film distributor 30 can associate film broadcasting right with particular online eye screens, namely, films are limited to be played on said online screens only. Film distributor 30 can also decide whether to limit playing times and/or playing period. When a download/play program is running, film distributor platform 32 checks the identification code of online eye screen 33 at first. If the identification code of online eye screen 33 corresponds with the identification code stored in film distributor platform 32, film transmission continues. If the identification code of online eye screen 33 does not correspond with the identification codes stored in film distributor platform 32, film transmission will be terminated. In this case, even if film data and film broadcasting rights (code or any other data to control the film data) are copied illegally, the corresponding films cannot be played on other devices. The said identification code can adopt physical identification code included into online eye screen 33 or registration number which is set by user 34 and stored in online eye screen 33.

In a preferred embodiment, film distributor platform 32 stores a user list (user database). The user list includes user information and identification codes of online eye screens 33 which are bound to corresponding users. User 34 (viewer) registers information of user 34 through visiting film distributor platform 32. After film distributor platform 32 checks the information of user 34 automatically or manually, user 34 becomes a registered user of corresponding distributor 30. Online eye screen 33 has mobile communication capability and web-surfing capability. Web-surfing means that online eye screen 33 can access the internet and perform functions such as searching and accessing different web sites. Online eye screen 33 is set with an identification code which is able to be visited and identified by film distributor platform 32. Identification code of online eye screen 33 is unique, for example identification code can be IMEI (International Mobile Equipment Identification Number) or MEID (Mobile Equipment Identifier). A specialized identification code can also be set for online eye screen 33. The specialized identification code is distributed globally in a unified way and recorded in online eye screen 33 by equipment manufacturers, wherein the specialized identification code is unchangeable. Each national government can set corresponding administrative privileges according to conditions, laws, bilateral trade agreements and multilateral trade agreement of the country. Distributor 30 distributes film data and film broadcasting rights through film distributor platform 32. User 34 visits film distributor platform 32 through a special online eye screen and sends a request for downloading film data to play online or store in local-storage. Film distributor platform 32 acquires the identification code of online eye screen 33 and checks the user list to obtain the user's registration information bound with the identification code. Film distributor platform 32 charges according to charge mode which film distributor 30 and user 34 previously have an agreement on.

In free mode, film distributor platform 32 selects to set several conditions to gain the said film broadcasting right for free. If film distributor platform 32 selects to set no condition for users to gain said film broadcasting right for free, film distributor platform 32 sends film data to any online eye screen which requests for film data. If film distributor platform 32 sets a plurality of conditions (for example, online eye screen which requests for film data for first time, online eye screen in a specific area or online eye screen used by an identified free user) to gain said film broadcasting right for free, online eye screen 33 sends a request to film distributor platform 32. Before and/or during the process of transferring film data, film distributor platform 32 verifies whether online eye screen 33 matches the set conditions. If online eye screen 33 matches the set conditions, film distributor platform 32 starts to transfer film data and/or continues to transfer film data to online eye screen 33. If online eye screen 33 does not match the set conditions, film distributor platform 32 does not transfer film data to online eye screen 33 and/or stops transferring film data to online eye screen 33.

In paid mode, any one or more ways below can be used to pay the film broadcasting rights.

(1) User 34 purchases the film broadcasting rights and gains the film data through online eye screen 33 or any other terminals. In the process of requesting for transferring film data, online eye screen 33 sends the film broadcasting rights data to film distributor platform 32. Film distributor platform 32 compares the film broadcasting rights data received from online eye screen 33 with film broadcasting rights data (real or legal film broadcasting rights data) stored in film distributor platform 32. Film distributor platform 32 identifies whether the film broadcasting rights data of online eye screen 33 are real based on the comparison. If the film broadcasting rights are identified, film data transmission is continued. If the film broadcasting right are not identified, film data transmission is terminated.

(2) User 34 uses online eye screen 33 to pay film distributor platform 32 and gains the film broadcasting rights. Film distributor platform 32 reads identification codes of online eye screen 33 or receives external input identification data automatically (i.e. identification data can be identification codes of online eye screen 33 or any other forms of identification data).

Film distributor platform 32 verifies whether online eye screen 33 is in the data base based on the comparison. If the online eye screen is in the data base, film data transmission is continued. If the online eye screen is not in the data base, film data transmission is terminated.

(4) When user 34 becomes a registered user, the corresponding film broadcasting rights are gained in a pre-paid mode. When film distributor platform 32 receives a request for film data from online eye screen 33, film distributor platform 32 recognizes the registered user associated with the online eye screen 33 is a pre-paid user and checks the account balance of the user. If the account balance is enough to pay for a film broadcasting right, film distributor platform 32 transfers film data to online eye screen 33, and deducts the corresponding fee for the corresponding broadcasting right from the account balance of the registered user. If the account balance is not enough to pay for the film broadcasting right, film distributor platform 32 sends out a message to online eye screen 33 to remind the user the account balance is not enough to pay for the film broadcasting right and does not transfer film data to online eye screen 33.

(5) When user 34 becomes a registered user, the corresponding broadcasting rights are gained in a post-paid mode. When film distributor platform 32 receives a request for film data from online eye screen 33, film distributor platform 32 recognizes the registered user associated with the online eye screen 33 is a post-paid user. If user 34 matches conditions set by film distributor 30 or if there is no condition, film distributor platform 32 transfers film data to online eye screen 33 and records the cost of the film into user's post-paid account. Preferably, user's account is bound with the user's personal bank account. User 34, film distributor platform 32, a bank (if necessary) and other corresponding relevant parties reach an agreement. When user 34 is registering on film distributor platform 32 or when user 34 has successfully registered on film distributor platform 32, user 34 inputs the personal bank account information at the same time. User 34 authorizes film distributor platform 32 to transfer related expenses from user's personal bank account. Film distributor platform 32 records the information of user's personal bank account. After online eye screen 33 receives film data, film distributor platform 32 sends the price of the film broadcasting right to a bank computer system. Film distributor platform 32 sends a request to the bank computer system to transfer the charge from user's personal bank account. The bank computer system verifies the request and transfers the charge from user's personal bank account to the bank account of film distributor platform 32.

User 34 visits film distributor platform 32 through a special online eye screen and sends a request to film distributor platform 32 for transferring film data. Film distributor platform 32 reads the identification code of online eye screen 33 and checks the user list to obtain the user's information bound with the identification code automatically. Film distributor platform 32 charges according to charge mode recorded in the user list. In a pre-paid mode, film distributor platform 32 checks account balance of user 34. If the account balance is enough for a film, film distributor platform 32 transfers film data to online eye screen 33. If the account balance is not enough for a film, film distributor platform 32 sends out a message to online eye screen 33 to remind the user the account balance is not enough to pay for the film and does not transfer film data to online eye screen 33. In a post-paid mode, if user 34 matches conditions set by film distributor 30 or if there is no qualification, film distributor platform 32 transfers film data to online eye screen 33 and records the cost of the film into user's post-paid account.

If online eye screen 33 has not captured signals of human body for a specific period set by the user, online eye screen 33 then locks the function of video playing.

The active connection types involved in present invention are based on existing technologies. For example, a relative linear movement (including the push-pull way stated above) is achieved by a guide rail, a guide rail slot and other support structures. Devices connected with the guide rail move along the guide rail slot, thus distance between devices can be adjusted. Adjusting devices such as screw and nut, rack and pinion and conveyor belt can be used to realize the relative linear movement.

A relative rotational motion is achieved by fastening one device on the shaft into the other device using bearing(s).

Related limit structures also use existing technologies. For example, baffle or blocks set on the motion curve (end point or limit point) of device can limit the motion of device. When two devices are required to achieve both relative spinning motion and relative linear movement, a middle connector is needed. One device first connects with middle connector through a spin connection. Then a middle connector connects with the other device through a linear connection. In this case, two devices are connected with each other in such a way that relative linear movement and relative spinning motion can be achieved. When a first part is fixed to a third part and a second part is movably connected to the third part, that means the second part is movably connected to the first part. The back and forth motion, left and right motion stated in present invention are all linear motions in corresponding directions.

Each of measures stated in the present invention can be combined freely except as stated otherwise to form different embodiments to meet different requirements.
